Our high-efficiency pumping solutions work seamlessly with modern irrigation systems for agricultural and non-agricultural applications and can operate with on- and off-grid energy sources.
Pumping systems for all types of irrigation systems
For the modern farmer, energy is often the highest single cost item. Grundfos supplies agricultural irrigation pumps that meet the low pressure and even flow requirements for uniform and efficient irrigation. Our pumping expertise and technology ensure uniform coverage despite fluctuating conditions, with pump efficiency optimised to reduce energy costs for running irrigation pumps, one of the highest single expenses for the farmer.
Pumps supplied for pressurised irrigation systems are perfect for sprinkler irrigation and drip irrigation. Variable speed pumps and easily integrated controllers automatically react to changing conditions and demands to keep running costs down.
Whether your water source is surface or groundwater, your pumps powered from the grid or solar panels or there is a need for water treatment, Grundfos has a solution for you. We supply fermigation and chemigation systems for agricultural irrigation, solutions for turf irrigation and mixers to ensure optimal biological processes for handling manure from livestock.
What is a cooling jacket and when should it be used for submersibles?
A cooling jacket, also referred to as a flow generator, ensures that there is always sufficient water flow across the motor surface in order to cool the motor.
In a typical well installation, the pump is surrounded by the walls of the well. The motor is installed below the pump. Because the pump draws in water from below, the water flows along the well walls and over the surface of the motor, cooling the motor in so doing.
If the pump is installed in open water, there will ...
What is the maximum sand content of pumped water for submersibles?
The maximum sand content of the water may not exceed 50 g/m³. A greater sand content reduces the service life of the pump and increases the risk of pump blockages.
